Where this fits
Use this page when you need the conversion step itself. If you already know sensitivity and specificity, go to likelihood ratio. If you want the full update, open Bayes theorem or pre/post-test probability.
FAQ
What does this page convert?
It converts probability into odds, and odds back into probability. That helps when you need to move between Bayes-style probability updates and likelihood-ratio workflows.
Why do I need odds at all?
Likelihood ratios multiply odds, not raw probabilities. Converting between the two makes Bayes updates easier to explain and audit.
Does the share URL include my numbers?
No. The share URL stores only light settings such as mode and decimal places. Numeric inputs stay in your browser.
Is this a betting-odds page?
This page uses statistical odds, especially for Bayes and diagnostic interpretation. It does not cover bookmaker formats such as decimal or fractional betting odds.
